Even while living in the same palace, he barely interacts with Arnold Hein, his older brother. Theodore’s odd behavior, like sleeping in Rishe Irmgard Weitzner’s garden and evaluating the soil for comfort, leads to a series of dramatic events that ultimately reveal his attempt to protect his brother in an unusual way.

The Warning Letter

He tries to warn her, saying “Arnold will kill you,” but Rishe quickly dismisses his warning.

The Kidnapping Incident

When Rishe collapses from overwork, Theodore tries to kidnap her with the help of Elsie.

However, Rishe escapes on her own thanks to her skills, and Theodore’s plan fails.

His Real Motive
